Dislocations in oxides such as cerium dioxide, a solid electrolyte for fuel cells, turn out to have a property that is the opposite of what researchers had expected, according to a new analysis at MIT.

One of the major drawbacks of carbon-fueled battery cells is the intrinsic presence of CO2, which impedes CO oxidation and, therefore, lowers the energy density of the cell. In the journal Angewandte Chemie, resear ...

By taking advantage of the natural tendency of chromium atoms to avoid certain bonding environments, scientists at DOE's Pacific Northwest National Laboratory have generated a material that allows oxygen ...

One of the applications that fuel cells may have is the supplying of homes with electrical power. When considering applications of this type that call for greater power, a research group in the UPV/EHU's Department of Mineralogy ...

(Phys.org) —Fuel cells for decentralized energy production require oxygen ion conductors: materials that can store oxygen as ions, and then transport and release it. German researchers have now found an ...

The sensors team at DOE's National Energy Technology Laboratory is working on sensor technologies to enable embedded gas sensing at high temperature. The team's goal is to develop novel materials with large ...

Research team of Ulsan National Institute of Science and Technology (UNIST), Georgia Institute of Technology, and Dong-Eui University developed a novel cathode material which has outstanding performance and ...

A formation mechanism of nanocrystalline cerium dioxide (CeO2), a versatile nanomaterial, has been unveiled by scientists from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) and the University of New South ...

(Phys.org) —Wouldn't it be great to have a magical "energy box" that could convert a wide array of fuels to electricity with high efficiency and lower emissions? Solid oxide fuel cells (SOFCs) show significant ...

(Phys.org) —Cubic zirconia has long been favored for its use in costume jewelry. Known scientifically as yttria-stabilized zirconia, it is also a known conductor of oxygen, making it useful as an electrolyte ...

New research at MIT could dramatically improve the efficiency of fuel cells, which are considered a promising alternative to batteries for powering everything from electronic devices to cars and homes.

(Phys.org) —In some parts of the developing world, people may live in homes without electricity or toilets or running water but yet they own cell phones. To charge those phones, they may have to walk for ...

New materials will have a central role in many of the energy applications of the future. For instance, inexpensive and environmentally friendly thermoelectric materials will be capable of converting waste ...

Researchers at AIST, Japan, have developed a handy, portable fuel cell system. While the developed system employs microtubular solid oxide fuel cells (microtubular SOFCs), a nanostructure-controlled electrode ...
